Occasional game of tennis in Mojacar?

Hi,

Long-time visitor to Mojacar (4-5 weeks per year) but new to this forum.

Are there any recommendations for playing tennis a couple of times when here?

I know there are courts in the Parador, and near La Mata / the Garden centre, but unsure of membership requirements etc.  IIRC La Parata is also subject to an annual membership fee, which probably doesn't make sense for a few games per year.

Thanks in advance,

Andy
